Well you can't 'control' them persay from inside the cockpit. The inner doors open to allow the gear to drop, then retract closed (as discussed above). The cycle reverses for the gear to go up. As for 'controlling' them, if you pull the emergency gear door handle the inner doors will stay open. If that handle isn't fully seated, it is possible a plane could take off and not get a positive up/locked on all 3 gear and the door. After a rash of unsafe gear indications maintence tried to blame the situation on pilots either not fully seating the handle, or resting gear on the handle. From the pilots perspective neither was possible. The relationship b/w the two seems correct though; they would say the opposite.
Mx: "Stupid pilots. Hanging gear from the Emergency Gear Handle" Pilots: "Stupid Mx. Can't fix the jets, and blaming it on us."
Comparable to all the IPs commenting on the great Mx vs Ops grudge.
